If a is the edge length of a unit cell, then correct option (s) is/are

Answer»

for simple CUBIC lattice, RADIUS of METAL ATOM `=a/2`
for bcc lattice, radius of metal atom`=(sqrt(3)a)/2`
for fcc lattie, radius of metal atom `=a/(2sqrt(2))`
distance between nearest neighbours for fcc `d=(sqrt(3)Q)/2`

Solution :For bcc lattice, radius of metal atom `=(sqrt(3))/4`
For fcc lattice, distance between nearest neighbours d
`=a/(sqrt(2))`
